DWIGHT RUSSELL, OF MILFORD, MASSACHUSETTS.

lM PROVEM ENT IN VAPO RINHALERS.

Specification forming part of Letters Patent No. 50,735, dated October 31, 1865.

To alt whom it may concern.-

Be itknown that LlDwIGH'r RUSSELL, M. D., of Milford, in the county of Worcester and State of Massachusetts, have invented an Imi proved Instrument for the Inhalation of Medicated Air or Vapor, such instrument being specially useful in the cure or alleviation of catarrh or various other diseases of the mucous membranes ofthe human system; and I do hereby declare the said invention to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a side elevation; Fig. 2, a front view, and Fig. 3 a longitudinal section of it. Fig. ais a top view of its nose-jets. Fig. 5is a section of such jets.-

The whole of the said instrument is to be made of glass, porcelain, or other suitable material, glass being preferred.

A represents a glass bottle or vessel provided with a long tubular neck, a, which atits top terminates in two branches orjet-tubes, b b, which are to be formed so as to fit into the nostrils of a person. Each of the branches b is open at its upper end, as shown at d. A tube, c, leads out of the bottom of the vessel A, and is formed with a bend,f, and thence turns upward alongside of the vessel A in manner as shown in the drawings, such tube being open at its upper end. There is also a hole, e, made through the side of the vessel A in a convenient position to be covered by the index-finger of a persons hand when grasping the vessel A and applying the branch-tubes to the nostrils.

From the above it will be -seen that my inhaler has no open mouth to receive a stopper and the nasal and air tubes, as is the case with most it' not all the inhalers, but the nasal jets or branches b b are applied directly to and are a continuation of the neck a; and,furthermore, the air-supplying tube c ot' my inhaler, instead of being introduced into the neck ot' the vessel to hold the liquid for medicating the air during the process ot' drawing it into and through the vessel, passes out of its bottom, and so curves upward or has a duplex Hexure, f, that the liquid poured through such tube and the vessel A will stand inf both of them and in the ieXurej'.

This arrangement ot the tube enablesa very small quantity ot' liquid to be used in the vessel and greatly increases the distance for the passage ot' air through the Huid with respect to what would result were the air-pipe to enter the vessel 'in the ordinary manner. Besides, with my arrangement of t-he tube c it may bc employed as a spout for discharging the fluid from the vessel A as well as for conducting fluid into such vessel. During the inhalation ot' air by a person he is to place on the hole e his foreiinger of the hand by which he may have hold of the vessel. Should the vapors inhaled be too pungent, he can, by raising his finger oftl the hole, let fresh air into the vessel, and thereby modify the vapors or mix air with them so as to diminish their potency.

I do not claim an inhaler as made with nosetubes to project from an air-inlet tube to cX- tend into the liquid-holding part or vessel.

I claim- The improved inhaler as made of one entire piece of glass,in mannersubstantially as specilied.
